Monarch Caterpillars

Monarch eggs are hatching. This newly emerged Monarch caterpillar is one day old. Its first meal is its egg shell. This is followed by eating a hole in the middle of the milkweed plant. Over the next few weeks this caterpillar will grow over 2,000 times this size feeding exclusively on milkweed leaves. It will undergo 5 molts, known as instars until it reaches full size.
